Subject: regression: b43-sdio: probe of mmc0:0001:1 failed with error -16
Date: Sun, 31 Oct 2010 18:16:04 +0100 [thread overview]
Message-ID: <4CCDA454.708@arndnet.de> (raw)
Hi,
on todays Linus' git (v2.6.36-9871-g3985c7c) b43 sdio stopped working.
It was working on (v2.6.36-6794-g12ba8d1).
b43-sdio: probe of mmc0:0001:1 failed with error -16
The error seems to originate from the following code in drivers/mmc/core/sdio_bus.c:sdio_bus_probe()
135 ret = pm_runtime_get_sync(dev);
136 if (ret < 0)
137 goto out;
so I suspect this has something to do with the following commit:
commit 40bba0c1ca83a370f749c8bc9afda71cf79ebd91
Author: Ohad Ben-Cohen <ohad@wizery.com>
Date: Sat Oct 2 13:54:11 2010 +0200
mmc: sdio: enable runtime PM for SDIO functions
However, simply reverting 40bba0c1ca83a370f749c8bc9afda71cf79ebd91 does not work because then
modprobe hangs.
Tested on AP4EVB (arm) with tmio_mmc. Any ideas?
Best regards,
Arnd
